"I always add the options "skip-m4" and "use-files" because I don't
want any of the M4 generated footprints, ever. But this may be due
to personal prejudice."
This brings up another issue I am having....As a neophyte to this tool
set (but not to EDA tools in general), what is the deal with m4
files? I've read through a lot of stuff in this area, dating from
2003 through now, and I still don't know if m4 files are good/bad? to
be used/avoided?
I am attempting to put a EDA workbench together in a reasonably
integrated way. Part of this is to create a (local) big symbol library
so that it can be used and managed. What I don't want to do is grab
component and footprint libraries that are old, brittle, or cause
gschem or PCB to die.
From my perspective, all of the inconsistent information is very
confusing. Quite simply, where is the 'best' symbol and footprint
library and the best way to create compatible symbols and footprints?
(After going through 3 different methods of generating symbols, it
seems that creating one graphically within gschem is the one least
laden with holes...true?)
Thanks to all who replied to my previous questions.

This is easier than not using the default lib at all. For gschem and
gsch2pcb
put the following lines in your user gafrc:
/----------- $HOME/.gEDA/gafrc ------------------------
;(reset-component-library) ; don't use system symbols
;(reset-source-library) ; don't use system location for
subcircuits
; Allow to source symbols from the current working directory
(define current-working-directory ".")
(component-library current-working-directory "symbols in project
dir")
(source-library current-working-directory)
; Allow to source symbols from the local copy of geda-symbols
(define symbols "FULL-PATH-TO-YOUR-SYMBOL-DIR")
(component-library symbols)
; In case you have symbols in subdirs you can build additional paths
on
; the fly. This example is for symbols/analog/diode
(component-library (build-path symbols "analog" "diode"))
; This statement makes gschem automatically enter subdirs:
(component-library-search symbols)
\----------------------------------
To make gsch2pcb find your footprints, add the following to your
project
file:
/-------------- YOUR-PROJECT.g2p -------------------
schematics YOUR-PROJECT.sch
output-name YOUR-PROJECT
elements-dir
FULL-PATH-TO-THE-DIR-BELOW-THE_DIRS-THAT-CONTAIN-YOUR-FOOTPRINTS
\---------------------------------------------------
I always add the options "skip-m4" and "use-files" because I don't
want any of the M4 generated footprints, ever. But this may be due
to personal prejudice.
To get your footprints in the PCB chooser edit the library line in
$HOME.pcb/preferences while there is no instnce of PCB running:
library-newlib = FULL-PATH-TO-THE-DIR-ETC:./footprints:.
Note, that unlike with gschem/gnetlist, you have to provide the Dir
below
the dir that actually contains the footprints.

IMHO, your set-up is perfectly fine :-)
Hope, this helps.
